AUTO-VALVE LIFTER.

Specification of Letters Patent.

Patented June 8, 1920.

Application filed August 25, 1919. Serial No. 319,524.

To all whom it may concern:

Be it known that I, Enunn E. I'IARRIS, a citizen of the United States,residing at Memphis, in the county of Shelby and State of Tennessee,have invented new and useful Improvements in Auto-Valve Lifters, ofwhich the following is a specification.

This invention relates to devices for lifting automobile valves, and theprincipal object of the invention is to provide an adjustable deviceadapted to be placed between the spring cup of the automobile and anadjacent part of the engine so that it is not necessary to providesuspending means for attaching the device to a part of the engine as isnow the case.

Another object of the invention is to provide two jaw members and athird member provided with a wedge part for forcing the jaw membersapart.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure 1is a View of the invention with the jaw member in closed position;

Fig. 2 is a view of the device with the jaws in open position;

Fig. 3 is a top plan view;

Fig. l is a bottom view;

Fig. 5 is a section on line 5-5 of Fig. 2;

Fig. 6 is a section on line 6-6 of Fig. 2.

In these views 1 indicates the stationary or main jaw member which isprovided with the handle part 2 and the ears 3 which are locatedintermediateits ends. 4 indicates the movable aw member which has itsrear end curving downwardly and is pivoted between the ears, as shown.Each jaw part is forked, as at 5, to receive the valve stem and theouter face is roughened or corrugated as at 6 to prevent slipping. Themain jaw part is provided with the rack teeth 7 and the movable part isprovided with the semicircular grooves, and said movable part is alsoprovided with a curved recess 9 on its inner face which is formed bycurving the jaw part as at 10. This movable part is slotted, as at 11and the shank 12 of the actuating member 13 passes through this slot.This actuating member carries at its end the wedge-shaped block 14 whichis rounded at its upper end to engage the grooves 8 and recess 9 and hasa square edge at its lower end for engaging the teeth 7.

The parts are assembled by passing the shank of the actuating member 13in the slot 11 of the movable jaw 4 before the same is connected to theears. Said movable jaw is then pivoted to the ears so that the parts areall connected together. In using the device the actuating member 13 isswung upwardly so as to permit the jaw members to contact with eachother as shown in Fig. 1. The ends of these jaw members are insertedbetween the spring cup and the adjacent part of the motor and then bypressing the actuating member 13 downwardly to cause the block 14 toassume a substantially vertical position, the jaw members will be forcedapart and thus raise the cup and spring to permit the removal orreplacement of the pin which holds the cup in position so that the valvemay be removed. The device may remain in this position while the valveand its seat is being ground. It will be seen that by placing the blockin the different grooves and teeth the extent of movement of the jawsmay be varied. lVhen the jaws are closed the block will engage therecess 9.

It is thought from the foregoing description that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims.

lVhat I claim is 1. A device of the class described comprising a pair ofjaw members, a handle connected with one member, an actuating deviceslidably connected with one jaw and means carried thereby for forcingthe jaws apart.

2. A device of the class described comprising a main aw member having ahandle connected therewith, a movable jaw member pivoted to the main jawmember intermediate its ends, an actuating member, a block thereonengaging between the members and adapted to be tilted by the actuatingmen1- ber for forcing the jaws apart.

3. A device of the class described comprismg a mam aw member havmg ahandle thereon, a movable aw member plvotecl to said main jaw member andhaving a slot 5 therein, said members having recesses formed thereln andan actuatmg member extencllng through sand slot and havmg an enlargementat its end resting between the jaw members and adapted to engage thereeesses When the acne-ting member is moved 10 to force and hold thejaws apart.

In testimony whereof I affix my signature.

ELMER EARL HARRIS.
